an axis;
a cap having a first circular top wall and a first skirt extending downwardly from a periphery of the first circular top wall to a lower edge of the first skirt, the first skirt including an inner surface having a sealing formation, an outer surface opposite the inner surface, a first detent coupled to the first circular top wall, a first formation formed on the outer surface, and a tamper band attached to the lower edge of the first skirt by a plurality of frangible members, the sealing formation configured to couple the cap to the container neck, the plurality of frangible members providing a visual indication, when broken, that the closure has been opened, the cap centered on the axis, the cap including an annular sidewall extending downward from the first circular top wall, the annular sidewall configured to interface against the container neck to seal the opening of the container neck; and
a cap cover including a second circular top wall, a second skirt extending downwardly from a periphery of the second circular top wall, the second circular top wall and the second skirt defining an interior having a second detent and a second formation formed therein, the second detent configured to engage with the first detent such that the cap cover is biased from being vertically removed from the cap as a result of the engagement between the second detent and the first detent, the second formation configured to engage with the first formation of the cap such that the cap is biased from rotating relative to the cap cover in both rotational directions as a result of the engagement between the second formation and the first formation, the cap cover enclosing at least a portion of the cap when the second detent is engaged with the first detent, the cap cover centered on the axis, the cap cover including one or more mating detents extending downward from the second circular top wall, the one or more mating detents circumferentially surrounding the first circular top wall of the top wall, the one or more mating detents being radially further from the axis than the annular side wall of the cap, and the one or more mating detents located above the second formation of the cap cover.
